Everyone has a mobile phone, and everyone is becoming more and more inseparable from the mobile phone. The function of the mobile phone is becoming more and more powerful. And the tempered glass film is
used to protect the mobile phone screen. Now, today Shirley will
introduce to you whether the tempered glass screen protector is drop-proof and the advantages of tempered glass film.
一、Is the tempered glass screen protector drop-proof?
Tempered
glass protective film is drop-proof. The thickness of this protective
layer is only 0.1 mm, which can completely cover the original screen surface, prevent damage from external forces and scratches, and increase shock absorption. Compared with PET film, Standard is 5 times higher. It does not affect the video effect of the screen. Super anti-scratch, wear-resistant, explosion-proof,
waterproof, anti-oil pollution, automatic air bubble elimination,
anti-bubble, anti-bacterial, anti-glare, it can effectively reduce the
impact force, effectively prevent the screen from cracking, special
tempering treatment, and prevent the glass protective film from being
broken by impact and causing glass fragments to hurt the human body.
二、The advantages of tempered glass film
1. High-definition: The light transmittance is above 90%, the picture is clear, highlights the three-dimensional sense, improves the visual effect, and the eyes are not easy to fatigue for use a long time.
2. Scratch-resistant: The glass material is tempered at a high temperature, which is much higher than that of ordinary film.
The common tools, keys, etc. in daily life will not scratch the glass
film. But the plastic film is different, scratches will appear after
several days. The things that can scratch them can be seen everywhere,
such as keys, knives, zippers, buttons, pen tips, and so on.
3. Automatic lamination: Align the tempered film with the mobile phone, and put it on automatically, without any skill, it will automatically adsorb.
4. Buffering: For mobile phones, tempered glass can play a buffering and shock-absorbing role. If the fall is not serious, the protector film will break, and the screen of the mobile phone will not break.
5. Ultra-thin design: The thickness is between 0.15-0.4mm. The thinner it is on the phone, the less beautiful it will be. The ultra-thin glass will be attached to it as if it fits perfectly with your phone.
6. Anti-fingerprint: The surface of the glass film is added with a coating treatment to make the touch smoother, so that nasty fingerprints are no longer easy to remain, and most of the plastic film is relatively jerky to touch.
Earphones are a necessity in life. When we are in the supermarket, we will find that different earphones
have different prices. They all say that there is one cent for one
cent. Then, of course, the earphones also have good and bad quality. So
what's the difference between the good and bad of our most commonly used headphones?
First of all, let's start with the workmanship and materials of the earbuds. This can be felt by our eyes and hands. Generally, the original earphone cable is relatively flexible and soft, and the biggest advantage
of the original earphone is that it does not worry about compatibility
issues. The headset standard is not compatible with mobile phones, and
the remote control and microphone functions will be unavailable. Some
people may not be able to listen to songs or the sound is too low when they buy headphones. The original is never the case. The original earphone is called because all standards are made according to mobile phones, so its price is naturally more expensive.
Let's talk about its frequency response curve. The design of a good headset conforms to the contours of the human ear. It is very comfortable to wear and does not fall down, some people who like music like to buy some good headphones are not just because good headphones are more sturdy and durable than poor headphones. Another reason is that the sound quality of good headphones is obviously better.
Another important point is the signal-to-noise ratio. The sound coming from the headphones has a great impact on your own ears. There is no doubt that the signal-to-noise ratio of good headphones is much better than that of poor headphones. For example, if you are in a very noisy place, but you still want to calm down and do your own thing, then a good headset will help you because when you put it on, it will block the noise and calm your heart.
If it is a normal headset, you may still hear the noise but it will be
reduced a little. Some headphones may have a sound leakage phenomenon.
This may be a problem common to some ordinary headphones. When you are
wearing a headset, your music leaks out of the headphones. At this time, people around you will look at you with disapproval, and then we will feel very embarrassed. The embarrassment of good quality headphones will not appear.
As mobile phone become more and more
important, mobile phones have become a necessity in our lives. With the
development of this trend, most people nowadays will intsall a screen protector
on the phone screen, one is to prevent the phone screen from scratch,
and the other is to prevent phone screen from being accidentally
dropped.
Moreover, cell phone screen protector have evolved into different kinds and offer different functions. But now many people have doubts, will the mobile phone protective film affect the sensitivity of the device?
There have to say, now a mobile phone touch screen technology, most of the current mobile phone in order to pass the screen touch speed, through the sensitivity of the sensing, capacitive screen technology
is applied. This technology mainly uses the conductor characteristics
of the human body and the interaction of the screen capacitance to
perform the sensing operation.
Simply
speaking, the human body is equivalent to an electrode. When the finger
touches the phone screen, the screen is inductively opposite to the
other electrode. The two sides meet to form a capacitor, and then the corresponding controller can accurately position the finger and perform corresponding Touch, to achieve accurate touch sensing.
Moreover,
because the sensing speed occurring in this process is very fast and
the sensitivity is high, this technology gradually replaces the
traditional screen technology and becomes the mainstream technology of
the current mobile phone screen application. But he also has a
disadvantage, that is, wet water can not be sensed.
Because water is also a kind of conductive body, the combined action of
the three parties will cause the induction to be not accurately
recognized.
Then
some people have said that the screen protector is not a conductive
material, so there is no influence on the touch of the mobile phone.
Although
this is true in theory, in fact, due to the different materials and
thickness of the protective film, it has some influence on the
sensitivity of the screen. Especially on screen fingerprint recognition,
the impact is more obvious. Nowadays, many smart phones use screen
fingerprint recognition technology. However, because the mobile phone
screen guard is not suitable after the screen protector is applied, or
the thickness is too large, the recognition accuracy is reduced, and sometimes the fingerprint recognition is not very sensitive.
Although
it is not excluded, there are still imperfections due to technical
screen fingerprinting. Now there is a more intuitive way to open the
phone settings, enter the developer options, then drop down to find "tap action feedback",
open, and then we can slide on the screen, the screen will show a small
ball With the movement of the finger, in the case of moving at
different speeds, by observing the different moving distance between the
ball and the finger, the delay phenomenon of the touch sensing of the
mobile phone screen can be seen.
However, many mobile phone films now have less and less impact on mobile phone fingerprint recognition and touch sensitivity. I believe that new technologies will bring better mobile phone experience to users in the future.
Mobile phones are an essential electronic product for us. In order to better protect mobile phones, most of us choose to attach a screen protector to our mobile phones. However, there are many kinds of mobile phone screen protective film on the market, such as anti-spy screen film, high-transparent screen film, matte screen film, etc., as there are so many kinds that we cannot choose the better one.
Today,
Lito will introduce you to the mobile phone screen protectors and their
respective characteristics, according to their characteristics, you can
choose the most suitable mobile phone protective film!
PET Film
Nowadays,
PET film is used less and less. Generally, the newly purchased mobile
phone will bring a PET film. The biggest advantage of this type of
cellphone screen protector is that it is cheap, but it is easy to scratch and the touching is not good. As for the hardness, the PET film has almost no hardness at all, and it is not shock-resistant.
In
addition, the PET film is not easy to install, and it is easy to appear
bubbles if it is not well attached. So we generally don't recommend the
PET film, unless it is emergency or not care about what screen
protector can be selected.
Tempered Glass Screen Protectors
The tempered glass screen protector is the most commonly used one. The tempered glass is the high-temperature treated glass. The hardness of the mobile phone screen protector made of this glass is greatly increased, and it is generally divided into a full covered tempered glass and a non-full coverage tempered glass.
Full covered tempered glass is suitable for many smartphones with 2.5D screens. The full coverage tempered glass film is more integrated, because the whole body is made of glass, so the hand feel
is also very good. The full cover tempered glass film with a frame
generally has a certain curvature, which can be wrapped around the edge
of the mobile phone to prevent the edges from being scratched and not easily broken.
The non-full-screen tempered glass is relatively simple, mainly protecting the middle screen
from being scratched, and basically does not affect the original feel
and color of the phone edge, portion of the mobile phone. However, since
the edge of the phone cannot be protected, if the edge is bumped, the
screen of the phone may be broken.
Nano TPU Film
Since the mobile phone is constantly updated, many curved screens have came out, and the nano TPU film has become popular. In fact, the essence of nano TPU film is also a plastic film, but the nano tpu film is a soft soft TPU film with a super flexible honeycomb structure. Different from the tempered glass, it is thick and hard. The Nano TPU film is thin and soft, it can 360 degree perfect fit the mobile phone, which is very suitable for curved screen mobile phones.
The advantages of the nano TPU film is that is can be covered in full screen. It is more resistant to fingerprints and oil than the traditional HD Film. It is lighter and softer,
and it can repair the slight scratches automatically. However, the
essence of Nano TPU film is still a plastic film, which is certainly not
comparable to the tempered glass screen protector in terms of hardness
and transparency.
In addition, there are many different mobile phone screen protector on the market to meet people’s needs.
Anti-Spy Screen Protector
The user of anti-spy screen protector can see the picture on the phone screen on the front side, while the others look at the screen on the side is black,
so it has the function of anti-peeping. However, the clarity and
transparency of this type of mobile phone screen protector is not high,
the screen is dark, and long-term use will also damage the eyes.
Anti-blue light Screen Protector
Because most mobile phones now have a Blu-ray filter mode,
you can also achieve anti-Blu-ray effects by reducing the brightness or
turning on the night mode. The ultraviolet light emitted by the phone
screen is negligible. Therefore, this type of mobile phone film that
mainly protects against blue light and ultraviolet rays is actually not
effective.
Back Screen Protector
There is also a mobile phone film that is a back film.
Most people now choose to wear a mobile phone case, but some people
think that the thickness of the mobile phone case affects the hand
feeling. If you want to protect the back cover of the mobile phone, you
can choose to apply the back film. The backing film is available in a
clear, matte and patterned decorative backing.
In
general, the choice of mobile phone film is not complicated, just to
find out your needs and preferences. Of course, the mobile phone screen
protector is not omnipotent. We should pay careful attention to the use
of the mobile phone during daily use to avoid violent impact on the
mobile phone, sharp scratching, water immersion and other injuries.
What are the disadvantages of oleophobic coating? What are the advantages of oleophobic coating?
The application of oleophobic coatings (also known as oleophobic layers)
is becoming more and more extensive. In addition to the surface of
precision instruments, many scenes requiring high cleanliness will also
adopt oleophobic coating. Of course, the oleophobic layer is known and
contacted by users most of the fingerprint lock screen and mobile phone touch screen.
The addition of oleophobic coating has many advantages, but there are
also some troublesome shortcomings. Now let me tell you more.
What are the advantages and benefits of oleophobic coating?
1.Keep clean, screen oleophobic coating generally uses nano-materials, using electroplating
process, forming a protective film on the screen surface, with
hydrophobic and oleophobic functions, oil stains are not easily
contaminated, easy to wipe, can effectively keep the screen clean.
2.Enhance the operation feel, the nano-material of the oleophobic layer has a smooth surface, smooth operation, does not increase the friction of the fingers, greatly reduces the obstruction phenomenon, and the touch is better.
3.To ensure touch sensitivity,
oil contamination will reduce the sensitivity of fingerprint
recognition, finger touch and other operational reactions, affecting the
use efficiency, oleophobic layer cleaning ability is the guarantee of sensitivity.
In addition, the oleophobic coating has the characteristics of low process cost, which provides the first conditions for mass production.
Although the application of oleophobic layer is extensive, it is not a perfect material and still has some shortcomings.
1.Poor wear resistance, screen oleophobic layer due to the requirements of the touch experience, generally, the thickness can be neglected, long-term high-intensity use will cause the phenomenon of shedding wear, thus greatly affecting the user experience.
2.The process standards are not uniform,
the process requirements of different screen surface oleophobic layer
are different, resulting in different quality and experience, and does
not meet the technical standards required for production and use.
The
abrasion of the oleophobic layer is a headache for many users. After
the oleophobic coating on the surface of the mobile phone screen or the
smart lock touch screen is worn away, it is recommended to purchase the
oleophobic layer to solve the problem, that is, the tempered glass screen protector and nano liquid screen protector, so we can protect our phone screen from any scratched.
What is hot-bend tempered glass screen protector and cold-engraved tempered glass screen protector?
Nowadays, the 3D curved tempered glass we know have two types:
Hot-bend and cold-engarved tempered glass, but how to select the suitable one for our mobile phones?
Do
you know the different between hot bending and cold carving? From the
price, it can be seen that hot bending tempered glass is more cheaper
than the cold carving tempered glass? But why?
The
same is the tempered glass screen protector, with different produced
technology, the effect of the tempered glass will be different. Hot-bend
tempered glass screen protector is softened by heating and then formed in a mold, and finally annealed, and the yield is higher than cold carving tempered glass.
The cold-engarved tempered glass is carefully carved by the CNC machine, which has a stronger of craftsmanship and a higher quality.
The tempered glass screen protector adopts the real screen opening mode, with the whole high-quality cold carving glass,
precise opening, accurate scale reduction, and the rounded corner
design of the 3D surface, so that the body curvature and the surface of
tempered glass is perfect fit the phone lcd screen, the integration is
stronger, just like the original phone. But cold carving tempered glass
has its disadvantage. Due to the deformation during the tempering
process, after the finished tempered glass screen film is formed, it is
easy to cause poor exhaust/unstable and difficult to exhaust.
The hot-bend tempered glass screen protector is mainly used to make a large curved edge tempered glass, the advantage of this technology is that the curvature of the curved surface is large and beautiful. The disadvantage is that the product has no texture overall, the hand feeling is not good, and it is easy to scratch hands.
Have you ever seen a rainbow effect in the tempered glass screen protector? Do you know why glass screen protector film have rainbow effect? And how do we eliminate the rainbow effect?
1.What is rainbow effect?
Here the rainbow effect we called is a phenomenon that generally appear arise at the surface of mobile phone screen protector, and it is similar to a rainbow.
2.The harm of rainbow effect
The harm of tempered glass rainbow effect is that it reduces the transmittance
of the screen protective film. It also causes the screen protector
convey the distortion of the screen color, and affects the our visual experience.
3.So why are there rainbow effect, do you all know the reason?
There are two reasons for the rainbow effect appearing after we installed tempered glass screen film:
First, the screen protection film is made of a multi-layer structure, and when the light is irradiated, the refraction produces a rainbow effect. On the other hand,
the "rainbow effect" is created because when the substrate needs to be
subjected to a high temperature during the hardening treatment. In the
high temperature treatment, the molecular structure of the substrate
surface is uneven to cause scattering.
The presence of rainbow effect affects light transparency and
visual effects. It is difficult to see the rainbow effect with the
naked eye after installation the high quality glass screen film. Rainbow
effect is actually the product of hardening treatment. The higher the
strength of the hardening treatment, the more difficult it is to control
the rainbow effect.
In
addition, when the PET substrate is subjected to surface hardened
hardening treatment, it is also susceptible to coating equipment and
curing materials. If the equipment and materials are improperly
selected, it is easy to cause uneven surface coating, which leads to
rainbow effect.
4.So, the rainbow effect is so much harmful, how do we eliminate the rainbow effect?
- Once the temperature rises to 35 degrees, the rainbow effect on the glass screen protector will disappear automatically.
- The screen protection film is pressed under high temperature environment, when it encounters a sudden low temperature,
it will lead to uneven local light transmission, resulting in rainbow
effect. When the temperature rises and the overall temperature of the
phone screen protector film tends to be the same, the rainbow effect
will disappear automatically.
- If it is a rainbow effect caused by the water
on the screen, then we don't have to worry too much, it will naturally
return to normal in a few days. If it is caused by external forces, then
here we suggest to buy a new screen protector.
